    • Activated human embryos produced by therapeutic cloning can give rise to human totipotent and pluripotent stem cells from which autologous cells for transplantation therapy are derived. The present invention provides methods for producing activated human embryos that can be used to generate totipotent and pluripotent stem cells from which autologous cells and tissues suitable for transplantation can be derived. In one embodiment, the invention provides methods for producing activated human embryos by parthenogenesis; in another embodiment, the invention provides methods for producing activated human embryos by somatic cell nuclear transfer whereby the genetic material of a differentiated human donor cell is reprogrammed to form a diploid human pronucleus capable of directing a cell to generate the stem cells from which autologous, isogenic cells for transplantation therapy are derived. The ability to create autologous human embryos represents a critical step towards generating immune-compatible stem cells that can be used to overcome the problem of immune rejection in regenerative medicine. The activated human embryos produced by the present invention also provide model systems for identifying and analyzing the molecular mechanisms of epigenetic imprinting and the genetic regulation of embryogenesis and development.
    • 通过治疗性克隆产生的活化的人类胚胎可以产生源自移植治疗的自体细胞的人类全能干细胞和多能干细胞。 本发明提供了用于产生活化的人胚胎的方法,所述活化的人胚胎可用于产生能够产生适合于移植的自体细胞和组织的全能干细胞和多能干细胞。 在一个实施方案中,本发明提供了通过孤雌生殖产生活化的人胚胎的方法; 在另一个实施方案中,本发明提供了通过体细胞核转移产生活化的人胚胎的方法,由此将分化的人供体细胞的遗传物质重新编程以形成能引导细胞产生干细胞的二倍体人原核,其中自体, 衍生出用于移植治疗的同基因细胞。 创建自体人类胚胎的能力代表了产生免疫相容性干细胞的关键步骤,可用于克服再生医学中的免疫排斥问题。 本发明生产的活化人胚胎还提供了用于鉴定和分析表观遗传印记的分子机制和胚胎发生和发育的遗传调控的模型系统。
